Vowel shift
The expected form for -shii adjectives derived from verbs is -ashii, as we see with. It is yet unclear why this term manifests an apparent shift from to.

There is an OJP-derived term and its phonological development, but the final -su in these is honorific, whereas verb-derived -shii adjectives appear to come from the causative form of the verb. Even so, honorific -su should also attach to the -a stem... Something is clearly going on here.

Curious if this is a manifestation of the theorized vowel pairing where stems indicate "external, apparent" and  stems indicate "internal, intrinsic".
